We look at the division of 986080 by 77 
We want to figure out the number of times 986080 can be divided by 77.

On to step 1:
The number 77 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 77

Step 2:
If we divide 98 by 77, we get 1 and a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 77 from 98 to get 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 77

Moving on to step 3:
If we divide 216 by 77, we get 2 and a remainder of 62.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 154 from 216 to get 62.
Grab the next digit (0) from the dividend, add it to 62, then carry on: 620 / 77

On to step 4:
The number 77 fits into 620 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 128.0
Deduct 616 from 620 and we're left with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 77

Going ahead to step 5:
If we divide 48 by 77, we get 0 and a remainder of 48.
The next digit of our result is 0. 
Result so far: 1280.0
Subtracting 0 from 48 leaves us with 48.
Fetch the next digit (0) from the dividend, attach it to 48 and continue: 480 / 77

Step 6:
77 can be fit into 480 6 times, resulting in a remainder of 18.
The next digit of our result is 6. 
Result so far: 12806.0
The remainder is 18 after subtracting 462 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
When dividing 180 by 77, we get 2 with a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 12806.2
If we take 154 away from 180, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 8:
77 goes into 260 3 times with a remainder of 29.
The next digit of our result is 3. 
Result so far: 12806.23
Subtract 231 from 260 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 9:
When dividing 290 by 77, we get 3 with a remainder of 59.
The next digit of our result is 3. 
Result so far: 12806.233
If we subtract 231 from 290, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

After the division, we end up with 12806.233 and a remainder of 0.0059.
